Claims
- 1. A rapid setting adhesive exhibiting high bond strength toward at least stainless steel, polycarbonate type plastics, and tooth enamel containing about 50 parts by weight glycidyl methacrylate, about 50 parts by weight of a finely divided cured polymethylmethacrylate, about 50 parts by weight of a finely divided polyethylmethacrylate, about 100 parts by weight of a finely divided copolymer of approximately equal amounts by weight of methylmethacrylate and ethylmethacrylate, about 50 parts by weight of diethylene glycol dimethacrylate crosslinking agent, less than about 5 percent of a conventional peroxide polymerization catalyst based on the combined weight of the glycidyl methacrylate and the finely divided fillers, and a minor amount of a conventional accelerator.
- 2. An adhesive composition as defined in claim 1 in the cured state.
- 3. A rapid setting adhesive exhibiting high bond strength toward at least stainless steel, polycarbonate type plastics, and tooth enamel containing about 60 parts by weight 3,4 epoxybutylmethacrylate, about 40 parts by weight triethylene glycol dimethacrylate, about 100 parts by weight of finely divided cured polymethylmethacrylate, about 100 parts by weight of silica having an average particle size about 10-20.mu., less than 5 percent of a conventional peroxide polymerization catalyst based on the combined weight of the 3,4-epoxybutylmethacrylate and the finely divided filters, and a minor amount of a conventional accelerator.
